Hello,
Here's a set of patches that adds support for the DU found in the R8A7790 SoC.
Compared to the R8A7779 DU, the R8A7790 has a third CRTC, internal LVDS encoders and different output routing options.
These patches are targetted at v3.12 so there's no rush (but please don't take that as an excuse to skip reviewing them :-)).
Laurent Pinchart (24): drm/rcar-du: Add missing alpha plane register definitions drm/rcar-du: Use devm_ioremap_resource() drm/rcar-du: Add platform module device table drm/rcar-du: Don't ignore rcar_du_crtc_create() return value drm/rcar-du: Support per-CRTC clock and IRQ drm/rcar-du: Fix buffer pitch alignment drm/rcar-du: Clarify comment regarding plane Y source coordinate drm/rcar-du: Split LVDS encoder and connector drm/rcar-du: Split VGA encoder and connector drm/rcar-du: Merge LVDS and VGA encoder code drm/rcar-du: Rename platform data fields to match what they describe drm/rcar-du: Create rcar_du_planes structure drm/rcar-du: Rename rcar_du_plane_(init|register) to rcar_du_planes_* drm/rcar-du: Introduce CRTCs groups drm/rcar-du: Use dynamic number of CRTCs instead of CRTCs array size drm/rcar-du: Remove register definitions for the second channel drm/rcar-du: Move output routing configuration to group drm/rcar-du: Add support for the R8A7790 DU drm/rcar-du: Fix buffer pitch alignment for R8A7790 DU drm/rcar-du: Add support for multiple groups drm/rcar-du: Add support for DEFR8 register drm/rcar-du: Rework output routing support drm/rcar-du: Configure RGB output routing to DPAD0 drm/rcar-du: Add internal LVDS encoder support
